Nokia is already on the 5th version of Maemo, a platform which by any measure is non-functional but already 5 years in the making. After this investment, only one product is shipping and it’s something of a science experiment–a pre-beta product. Nokia is also on the 9th version of Symbian, a functional but outdated platform stuck in the 90s. Promising big things in the 10th version to be re-branded Symbian ^2–I guess double digit version numbers are not confidence inspiring.

Microsoft meanwhile is working hard on the 7th major version of Windows Mobile. World waiting with bated breath.
